## Abstract We study numerical approximations of solutions of the following system of heat equations, coupled at the boundary through a nonlinear flux: where __p__ and __q__ are parameters. We prove that the solutions of a semidiscretization in space quench in finite time. Moreover, we describe i
In this paper we consider a system of heat equations ut = Au, v, = Av in an unbounded domain R c RN coupled through the Neumann boundary conditions u, = up, v, = up, where p > 0, q > 0, p q > 1 and v is the exterior unit normal on aR. It is shown that for several types of domain there exists a criti
Under some natural hypothesis on the matrix P"(p GH ) that guarrantee the blow-up of the solution at time ¹, and some assumptions of the initial data u G , we find that if "" x """1 then u G (x , t)goestoinfinitylike(¹!t) G /2 , where the G (0 are the solutions of (P!Id) ( , )R"(!1, !1)R. As a corol
